To aZZ whom it may concern.-

Be it known that I, GEORGE WJWxrnns, a

citizen of the United States, residing at Kansas, in the county of Edgarand State of Illinois, have invented a new and useful Wheat Scourer andSeparator, of which the following is a specification.

This invention relates to machines for scouring wheat and other grainand for separating the same from dust and other impure particles; and ithas for its object to provide a machine of this class which shall besimple in construction and effective in operation without the necessityof running it at a dangerously high rate of speed.

Like numerals of reference indicate like parts in all the figures of thedrawings.

The frame'of my improved gram-scouring -n1aehine is supported uponsuitable legs or uprights 1 1, and is provided with cross-braces 2 2,connected by a sill 3, in which is stopped the lower end of the verticalshaft 4, the upper end of which has a bearing in a crosspiece 5, mountedupon uprights or brackets 6 6, rising from opposite sides of the frame.The latter consists, essentially, of a box 7 under the bottom of which afan-case 8 is arranged horizontally, as shown, the fan, which isdesignated by 9, being mounted upon the shaft 1.

1O designates a frame the sides of which are provided with bolts 11,extending through vertical slots 12 in the sides of the box or fan, andare provided with thumb-nuts 13, by means of which the said frame may beheld securely in any position to which it may be adjusted. The upperside of the frame is -20, communicating with the fan-case.

' covered with a stout netting 14, of steel wire,

which forms one of the scouring-surfaces of my improved machine.

15 designates a cylinder, likewise made of steel-wire netting. Saidcylinder is provided with a top piece or cap 16, and it has at its loweredge a flange 17 to receive bolts 18, by means of which the saidcylinder is securely connected with the vertically adjustable frame 10.The top piece 16 of the cylinder has a central opening 19, and thebottom of the frame or box is provided with an opening The bottom of thelatter is also provided with an opening 21 for the passage of the shaft4.

Suitably mounted upon theshaft 4, above the scouring-surface 14 andwithin the cylinder 15, is the beater cylinder or disk 22. The latter,which is provided with arms or spokes 23 by which it is mounted upon theshaft, has on its under surface a tangentially-arranged series ofbrushes 24;, and its perimeter is likewise provided with verticallyarranged brushes 25. The latter are mounted adjustablyin such a mannerthat they may be moved in an outward direction in order to compensatefor wear. The upper edge of the beater-cylinder has an annular flange26, which is almost in contact with the surrounding scouring-cylinder15, for the purpose of preventing the grain from escaping in an upwarddirection and blocking the space between the top of the beater-cylinderand the cap 16 of the scouring-cylinder. The latter is provided at oneside with an opening 27, surrounded by a frame 28, having verticalgrooves 29, for the purpose to be hereinafter set forth.

The beater-eylinderis provided with a flange 30, extending upwardly fromits inner edge through the opening 19 in the top piece or cap 16 andinto the box 7, terminating under the lid or top piece of the latter,which has the feed-opening 7". Said box is secured detachably to theframe by means of screws or bolts. The box or frame 7 is provided with abearing 32 for the upper end of a countershaft 34, the lower end ofwhich is stepped in a brace 35, connecting two of the legs of the frame,and having a drum 36, connected by a band 37 with a pulley 38 upon themain shaft 4. The latter is also provided with a pulley 39 to receivemotion from some suitable source of power. The upper side of the frameis provided with a pivoted vibrating chute 40, having anoppositely-inclined supply-chute 41, which latter is provided with ascreen 42, having openings of sufficient size to admit of the passage ofgrain, while sticks and similar obstructions are separated and carriedoff. The feed-chute 4O conveys the grain through the opening in theupper side of the box. The outer end of the compound chute 40 41 has aperforated bracket 44, resting upon an eccentric or canrsllaped shoulder45 at the upper edge of the counter-shaft 34, which latter thus impartsa vibrating motion to the said chute.

The box or frame of the machine 32 is provided with a discharge-spout47, communicating with the opening 27 in the scouring-cylinder. Avertically-movable gate or valve 48 is also provided, having flanges 49,that work in the grooves 29 in the frame 28 for the purpose ofregulating the escape of the grain from the machine.

The operation and advantages of my improved grain-scouring machine willbe readily understood from the foregoing description taken in connectionwith the drawings hereto annexed. The grain is fed through the feedspout or chute into the central opening in the beater-cylinder and dropsupon the netting 14, which constitutes the lower scouring-s11 rface. Thetangential brushes upon the under side of the beater-cylinder force thegrain gradually in an outward direction, the grain being turned over andover while moving outwardly toward the scouring-cylinder15. The verticalbrushes upon the edge of the beatercylindercarrythe grain around incontact with the scouring-cylinder 15, the grain being held in contactwith the latter by the centrifugal force until it reaches theescape-opening 27, where it escapes, the escape of the grain beingregulated by the gate or valve. At the same time the fan arranged belowthe scouring mechanism creates suction through the netting 14 andthrough the walls of the cylinder 15, thus separating the dust and smutfrom the grain and carrying it up through the side openingin thefan-case. My improved scouring-machine thus serves the double purpose ofscouring the grain and separating it from all impurities.

Having thus described my invention, what I claim is- 1. In a machine ofthe class described, the combination of a vertically-adjustable framehaving a scrubbing-surface of wire-netting with a beater disk orcylinder mounted upon a vertical shaft and provided on its under sidewith tan ge ntially-arranged brushes bearing against the saidscouring-surface and a suitable casing, substantially as set forth.

2. The combination of the vertically-adjustable frame having ascouring-surface of wire-netting, the scouring-cylinder mounted upon thesaid frame,and the beater disk or cylinder having the tangential and thevertically-arranged brushes and provided with a horizontal flange at itsupper edge, substantially as set forth.

3. In a machine of the class described, the combination of the casing,the vertically-ad justable frame having a scouring-surface ofwire-netting, the scouring-cylinder mounted upon said frame and havingan imperforate top piece or cap provided with a central opening, and thebeater-cylinder arranged within said scouring-cylinder and having anannular horizontal flange and an upwardly-extending flange projectingthrough the central opening in the cap of the scouring-cylinder,substantially as set forth.

4. The combination of the casing, the vertically-adjustable frame havinga scouringsurface of wire-netting, the scouring-cylinder mounted uponsaid frame, the beater-cylinder mounted upon a vertical shaft withinsaid scouring-cylinder and having a central open ing for the admissionof grain, the fan-case arranged below and communicating with the casingin which the vertically adjustable frame is mounted, and the fan mountedupon the shaft of the beater-cylinder, substantially as set forth.

5. The combination of the main casing, the fan-case arranged below andcommunicating with the same, a vertical shaft extending through andhaving bearings above and below said main casing and fan-case, thevertically-adjustable frame mounted in the main casing and having ascouring-surface and a scouring-cylinder mounted thereon, thebeater-cylinder mounted upon the vertical shaft within thescouring-cylinder and having a central opening for the passage of grain,an exit-opening in the side of the scouring-cylinder, and a fan mountedupon the shaft of the beater-cylinder, substantially as set forth.

6. The scouring-cylinder mounted upon a vertically-adjustable frame andhavinga discharge opening, in combination with the frame surroundingsaid opening and having vertical grooves, the vertically-movable gatehaving flanges working in the said grooves, and the casing having thedischarge-spout, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
